The current study examined how viewing nature vs. urban scenes impacts the duration of the attentional blink. Nature scenes produce a broader allocation of attention, allowing attention to spread and reduce the ability to disengage attention. Urban scenes produce a narrowed allocation of attention, allowing efficient encoding of relevant information, inhibition of irrelevant information and a speedier disengagement of attention. Participants viewed a rapid serial visual presentation (RSVP) of either nature or urban scenes. For both scene categories, an attentional blink was evident by reduced accuracy for reporting a second target that occurred two or three scenes after an accurately reported first target. However, the duration of the attentional blink was reduced for urban scenes compared with nature scenes. A peripheral target detection task confirmed a difference in the allocation of attention between scene categories. The peripheral targets were better detected for nature scenes, suggesting that participants have a broader spread of attention for nature scenes, even in an RSVP task. The shorter duration of the attentional blink for urban scenes was consistent across four experiments with small and large sets of urban and nature scenes. Therefore, urban scenes reliably reduce the attentional blink duration compared with nature scenes, and this could be attributed to a narrowed attention allocation that allows speedier disengagement of attention in an RSVP.
